Problems solved by technology
[0004] When the calling terminal has an abnormal situation, the calling terminal may use other encoding formats to encode the data carried in the sent data packet, and the called terminal cannot decode the received data using the negotiated encoding format, resulting in Decoding errors and exceptions during calls

Embodiment Construction
[0060] Reference will now be made in detail to the illustrative embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following illustrative examples do not represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.
[0061] In order to facilitate understanding of the embodiments of the present disclosure, a VoLTE call process is firstly introduced and described.
[0062] In an illustrative example, the VoLTE call process includes the following steps:
[0063] In the first step, the calling terminal sends an INVITE message to the call center through SIP (Session Initiation Protocol, Session Initiati...

The disclosure provides a method and device for determining a coding format, which relate to the field of communication technology. The method includes: receiving a data packet forwarded by a call center during a VoLTE call, the data packet carrying a first coding format; detecting the first coding format Whether it is the same as the second encoding format negotiated; if not, modify the encoding format used during the call from the second encoding format to the first encoding format; solve the problem of sending the calling terminal when using other encoding formats When the data carried in the data packet is encoded, the called terminal cannot decode the received data using the negotiated encoding format, resulting in decoding errors and abnormal problems in the call process; the first encoding format carried in the data packet is reached When it is different from the negotiated second encoding format, the received data packet is decoded by using the first encoding format to ensure normal call quality.
Description
technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a method and device for determining an encoding format. Background technique [0002] A VoLTE (Voice over Long Term Evolution, long-term evolution voice service) call refers to a network call between a calling terminal and a called terminal in the form of transmitting data packets. [0003] The VoLTE call process in the related art includes: the calling terminal sends a request message to the call center, and the request message carries the called number and the encoding format supported by the calling terminal; the call center forwards the received request message to the called terminal; The called terminal sends a request response to the calling terminal through the call center, and the request response carries the encoding format supported by the called terminal; the called terminal and the calling terminal negotiate through the call center to determine t...
